CULTIVATOR- Specification of Letters Patent Patented May 29, 19Q6.

Application filed August 8, 1905. Serial No 273,255.

To all whom it 77Q/(1/Z/ concern.-

Be it known that 1, JOHN P. HILL, a citizen of the United States,residing at Seffner, in the county of Hillsboro and State of Florida,have invented new and useful Improvements in Cultivators, of which thefollowing is a specification.

This invention relates to improvements in cultivators of that classembodying a main beam with adjustable supplemental or fly beams and anadjustable gage-wheel.

The primary object of the invention is to provide a cultivator in whichthe width thereof can be readily increased or decreased at will by theoperator to accommodate treatment of rows of plants separated bydifferent widths or spaces.

A further object of the invention is to provide a cultivator in whichthe cultivating devices or plows are so arranged as to follow each otherso that the furrow next to'the plants cultivated may be filled by theplow following to avoid leaving an open furrow next to the plants andprevent drying out of soil adjacent to the'latter.

A further object of the invention is to provide a simple and effectivemeans for adjusting the gage-wheel andv for applying a draftattachingmeans.

A still further object is to provide a simple and effective cultivatororganization of a strong and durable nature.

In the drawings, Figure 1 is a side elevation of a cultivator embodyingthe features of the invention. the same. Fig. 3 is a longitudinalvertical section through portions of the forward extremity of thecultivator. Fig. 1 is a transverse section on the line& 1, Fig. 2. Fig.5 is a detail view of a pulverizer attachment adapted to be substitutedfor a part of the cultivator.

Similar numerals of reference are employed to indicate correspondingparts in the several vlews.

The numeral 1 designates a main or cen tral beam, 2 supplemental or flybeams, and 3 side beams or members movably attached at their rear endsto the intermediate portions of the inner sides of the supplemental orfly beams and at their forward extremities secured to a cross-head 4,held onthe main or central beam 1. On the main or central beam 1 arefront and rear slide-boxes 5 and 6, secured to each other by straps 6and respectively connected, by means of links or adjust- Fig. 2 is a topplan view of formed with upper and lower members with an openingtherebetween (see Fig. 4) for movable passage of the side beams 3therethrough. This assemblage materially strengthens the links 9. Thelinks or adjusting-bars 7 and 8 are of such length that the supplementalor fly beams 2 will be held at angles of inclination with respect to themain or central beam 1 and converged rearwardly, as clearly shown byFig. 2. The rear end of the main or central beam 1 and the forward andrear extremities of the supplemental or fly beams 2 have cultivatingdevices of any suitable nature attached thereto, and it will beunderstood that any type of cultivating device may be employed, and thefastening means therefor will be so arranged that a substitution of onekind for another can be readily obtained.

The side portions or connecting members 3 have their rear extremitiescurved outwardly, as at 10, and secured thereto are cultivating devices12, one on each, similar to the devices 10, thus forming a cultivatorhaving seven plows or other devices 10 and 12. At

times the cultivating devices 12 may be omitted and the cultivator beused with five plows carried by the main or central beam 1 and thesupplemental or fly beams 2. i The boxes 5 and 6 are preferablyconnected by straps 63 for unitary adjust-ment or moved, as heretoforeexplained, and to the rear box 6 is attached a link-bar 14, which runsto an adjustingdever 15, cooperating with a toothed segment 16, held onthe rear extremity of the main or central beam 1, this adjusting-leverbeing provided with the usual catch-dog 17. By moving the lever 15forwardly the supplemental or fly beams 2 will be drawn inwardly towardthe main beam, and a reverseoperation of the adjusting-lever will resultin throwing the supplemental or fly beams outwardly, and by this meansdifferent degrees of adjustment may be obtained to space the cultivatingdevices or plows 10 and the cultivating devices 12 when used as maybedesired to accommodate a difference in width of rows of plants to becultivated. I

On the main or central beam 1, between the slide-boxes 5 and 6,rearwardly and outwardly inclined lugs or bosses 18 are mounted toreceive the lower ends of handles 19 of the usual form, the latter beingpreferably sustained by braces 20, running from the intermediateportions thereof downwardly and intermediately of the rear extremity ofthe main beam. The adjusting lever 15 will project upwardly between thehandles 19,

and the latter will be used as in ordinary cul- 'tivators.

It will be seen that the outwardly-curved rear extremities of the sideportions or connecting members 3 dispose the cultivating devices orplows 1.2, secured thereto, at points intermediate of the similardevices carried at the forward and rear extremities of the supplementalor fly beams 2, and all of the cultivating devices or plows are in suchrelation with respect to each other that the furrows made by the forwardones will be. covered by the next succeeding devices of a similarcharacter. To properly dispose the cultivating devices or plows on thesupplemental or fly beams 2, the front and rear extremities 21 thereofare formed straight and in parallel relation to the main or central beam1 or at "angles to the said supplemental beams. This structuralprovision permits all the cultivating devices or plows to form straightparallel furrows or to produce furrows parallel to the rows of plantstreated; but at the same time the supplemental or fly beams 2 aredisposed in angular position with respect to the main or central beam 1,as heretofore set forth, to obtain a compact organization of thedifferent parts of the cultivator and effectiveness in the adjustment ofsaid supplemental beams,

Rising from the front end of the main or central beam 1 is a post 22,having the rear edge for a portion of its vertical extent formed withteeth 23. To the upper end of the post 22 and to the main or centralbeam 1 in rear of the cross-head 41 a pair of spaced segmental braces 24are secured, and therebetween is disposed an adjusting-lever 25,fulcrumed to the braces through the medium of a fulcrum-pin or otheranalogous device 26. The adjusting-lever 25 projects rearwardly asufficient distance to be within easy reaching distance of the operatorat the rear of the cultivator, and carried thereby is a catch-dog 27 ofthe usual form and operated in a manner similar to devices of thischarac- -ter. The catch-dog 27 is adapted to engage the teeth 23 of thepost 22, and the forward end of the lever 25 is connected to rear flangeextensions 28 of a sleeve or swivel connection 29, through which extendsthe vertical stem' f-gous device 32, projecting downwardly under themain or central beam 1. On the upper end of the stem 30 and at asuitable distance below the upper end of the latter stop 1 tion aparticular form of clevis device consisting of a head 35, having aforwardly-projecting neck 36, upturned and directed rearwardly toproduce an attaching-hook 37 for application thereto of the usual draftappliances. The rear extremity of this clevis device is bifurcated orslotted, as at 38, to fit over or embrace the upper extremity of thepost 22 below the point of attachment of the segmental braces 24 to thelatter. The clevis device is held in connection with the post by a bolt39, passed therethrough and through the said post, and when the clevisdevice is applied it projects over the upper extremity of the swivelconnection for the gage-wheel without interfering with the latter. Bythe application of this clevis device as set forth and in conjunctionwith the gagewheel, the draft can be readily regulated to render thecultivating devices or plows effective in forming furrows of any depthdesired.

In advance of the front slide 5 the main beam 1 has a pair of openings40 formed therein for removable attachment of an extra plow-stock andplow when desired. Fig. 5 shows a pulverizing attachment 41, which isadapted to be substituted for each of the fly-beams 2. Other attachmentsmay also be applied to replace the fly-beams.

It will be understood that changes in the proportions, dimensions, andminor details may be resorted to without departing from the spirit ofthe invention.
